阻电机的构造

其中两个环短路。电机作为单相感应电机工作，直到定子与单相电源对齐。离心传输分离辅助绕组，直到电机输出接近大同步速度。通过主绕组操作，电机像单相电机一样加速。

一旦电机速度接近同步速度，转子就会倾向于在磁阻小的位置自行连接，从而产生扭矩。结果，转子同步拖动。为了获得适当的效率，负载惯性保持在可接受的范围内。感应转矩在同步时会消失，但由于同步磁阻时的转矩，转子将保持同步。

2.磁阻电机的优缺点

优势：

（1） 不需要直流电源。

（2） 特性稳定

（3）维护较少

（4） 热量少

（5） 无磁铁

（6） 速度控制

弊：

1）效率较低

2）功率因数差

3） 变频调速

4）这些电机的容量较小，无法驱动负载

5）需要较少的惯量转子。
